MACHINE FOR MIXING EXPLQSIVEE.

No.v 902,464.

T a all whom 'it may concern:

Be it known that I, HENRY Anci-m, a citi- .zen of the United States, residing at Emporiuni, county of Cameron, and State of Pennsylvania,have invented certain new and useful Improvements in Machines for Mixing Explosives, of which the following is a specification.

. My invention relates to machines for mixing explosives.

In an application for a machine for mixing explosives executed of even date here- 1 with, Serial No. 396,109 I 'have set forth a Y ploy, a strictly mechanical means for raising 1 and lowering the-mixing bowl' ofA th'is mixing maehineand the present invention has for its object the provision of novel means ofthis character whereby the attendant may raise and lower the mixing bowl by hand.

vThe invention contemplates the provision of novel means of the character set forth whereby a small amount of energy exerted by 1 theiattendant may be utilized to raise and.lower the heavy niixing bowl or recepta-cle with ease and facility, which is accomplished by providing eccentrics,l gearing` and aeounter-weight all of which are fully set forth hereinafter and embodied in the a ppended claims. l

In the accompanying drawingsz-Figure 1 is a front elevation; Fig. 2, a side elevation; Fig. 3, a detail 'section on line 33 ol' F ig. 2; Fig. 4, a vertical detail section of the mixing bowl and adjacent parts; and Fig. 5, a section on line 5 5 of Fig. 2.

'Ihe machine is supported by a. metal base 1 .which may have a suitable foundation and from which rise four hollow pillars 2 which Sustain a frame-work 3, tie-rods et running through the piece 1, pillars 2 and frainework 3 and rigidly tying the whole structu re together.

The mixing bowl or tub 5 is of elliptical form, being provided with a water space 6 surrounding it and extending beneath it in a well known manner, While in the space under the n'iixing bowl there is located a Steam coil -7 for heating the water whereby Specification o' Lettera Patent. Appncanoa inea oca-ber 5, ism. serial No. esame.

mania@ oo. ai, i908 the contents of the bowl are kept at the proper temperature. The-water space (i has a water inlet 8 and an outlet 9 which are connected to flexible hose sections 10 and-1.]e respectively. Similarly, the coil 7 has the point. The inlet l2 extends upwardlyand is connected to a flexible hose 14; receiving steam from any suitable source. 1

Secured to the laterally extending endpieces 15 of the bowl 5 are Woodenguides purpose` The guides 16 andl'have Sernicircular matchingholes which receive the pillars or columns2. Wood is used' to prevent heating from friction as the' guids .slide up and down on the pillars 2. The bolts'lS provide means for adjusting the guides 16 and 17 withV any desired degree of closeness of tit against the pillars 2.

Extending through openings in the endpieces 1 5 are vertical rods 20, suitably secured to the said vend-pieces, Ywhich pass u are coupled at -50 to links 51 of eccentric straps 52 which surround-eccentrica 53'secured to the shaft 54 mounted in bearing standards 55 rising from the frame 3. The shaft 51 carries a pinion 56. Pivoted on the stub-shaft. 57 projecting from frame 3, is a lever 58 whose lower end is provided with a' handle in convenientV position tobe grasped by the attendant for :swinging the lever a curved rack 59 meshing with the pinion 5 6, To the shaft 54 is secured a Isheave 60 to which is connected a cable 61 fromy which is suspended a counter-weight 6 2 of pro er avoirdupois to balance the mixing bow 5 and operating parts. The eable'tl passes over an idler` sheave 63. l

i sition, the cylindrical surfaces of. the buffers permitting it to drain o`.

l Secured on the pillars 2 are adjustable 16 and 17, bolts 18-being 'employedior warclly through the frame 3; The rods 'Q laterally and on its upper end provided with steam inlet 12 and an outlet or exhaust 13, The exhaust'13 may deliver the steam to any Extending cross-wise in relation to vthe lio construction, the blades having their faces -bumpers or buffers 2 9 which are positioned at 'the height to which it is desired the bowl 5 shall be-ralsed.

he mixers v36 aredetachably connected to the shafts34 vand are of apaddled or bladed inclined and those of one -mixer interacting However,

different forms of mixers may be employed if desired. jKey seated andrigidly con- `-nected by '-pins to the upper ends of the shaft 'upper' journal-boxes, 33 and meshing with bevel gears 39 carried by a shaft 40 jourshaft 44 so 34 are beveled gears 37 supported on-the .-nal'ed 'in boxes 41 on frame 3. The shaft 40 carries 'a friction-wheel 42 driven. by a correspondin wheel 32 loosely splined on a at it may be slid to any position crosswise of. wheel -42 to drive the latter faster or slower or reverse the-rotation thereof so thatvthe mixers afterhaving been rotated a. given time in o ne direction, may he "reversed, apractlee which is very beneficial '1n carrying out the mixing operation.

l It .being understood :that the-mixers and their shafts are incapable of up and down play and are not intended `for such movemen t,'the mixing operation wil-l be carried on by raising the bowlV 5 to cause submer-- gence-of the mixers in the liquid explosive Y in said bowl. In thisposition the bowl is at'such a height `that-the attendant can readily observe the -mixing operation and '.control the machine accordingly without inconvenienc'eor having to stoop over as is now t-he case wlth ltilxlng machines now lknown to the art. When the mixing opera- "tion is completed the bowl is lowered and the contents takenbfi. When so lowered .access can be' had to the mixers.

The raising and lowering of the. mixing bowl i's Very easily edected on account oi ille great ,power obtained by the use of the eccentrics aifording means whereby the mix- 1111receptacle willrcmam'm the position to cccentrics in, connection with the lever and rack and pinion 56, 59, the hand-weight and which 'it' is shifted by th'eopcralor..

',llhc eccentric mechanism will prevent a gi-eat,risc-,loridescent of the mixing bowl and-will 'lloltdit-with great precision at thc desireglgfpointiit 4the 'upper'or'lowcr end of its rum everytime it is' operated vso that no dangercan aniseifrom impactot the mixers against-thebottom of the mixing bowl ori violent deposit of the bowl on the buffers when it is lowered but will deposit the mixing bowl gently upon them, the eccentric mechanism sustaining the greatestportion of'the weight of the bowl and its accessories.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent is Y l. In a machine for mixing explosives, the combina-tion with a mixingr bowl,- of mixing'means adapted to operate iii-said mixing howl, said bowl and mixing means ering independently of their operation for mixing purposes, and means for accomplishing the relative raising and lowering of said bowl and mixing means independently of their operation for mixing purposes comprising an eccentric, an eccentric stra-p, and means for turning'the eccentric.
